ROLLER-BEARING.

1909. Serial No. 485,889.

- tain new and useful Improvements in Rollererence -is had to the accompanying Bearings, of which the fication.

The invention relates toimprovements in roller-bearings and in general construction following is a speciis adaptable to truck-wheels rotatable upon a fixed axle and for Hanger-boxes for supporting a rotating shaft.

The object of the invention includes certain details of construction whereby the several parts are securely retained in adjustment and held in conveniently detachable relation with one another to provide an .eflicient and durable bearing. I

In describing the invention in detail refdrawings, forming part of this specification, and wherein like characters of reference are used to designatelike parts throughout the several views, and in which:

Figure .1 is an end view of a roller-bearing v embodying the present invention and shown in connection with a portion of a hanger or supportlng-frame, the wall of the bearing; being broken away to show the interior arrangelnent of parts; Fig. 2, a longitudinal vertical section of the same; Fig. 3, a detail side view of the retainer for the rollers; and Fig. 4c is a longitudinal section of a modification of the bearing in its adaptation to a wheel rotatable upon a fixed axle.

In the drawings, numerals l and 2 designate respectively the upper and lower halfbox or casing of the bearing, providedwith Side connection-lugs 3 and 4, and detachably connected together by screws 5. The connection-lugs 4 of the lower half-box is of sufiicient .size and strength to receivze the pointed ends of the supporting-screws 6, the latter engaging screw-threaded perforations in the hanger-arms 7 and adjustably secured therein by the lock-nuts 8. \Vith the side walls of the box or casing are formed ledges side wall 12 is formed integral with the box for receivin the annular bearing-surfaces 0r wearing-sleeves 9, concentrically disposed with relation to the central shaft 10, arid detachably secured in place by screws 11 for convenient renewal in case of wear. The

ripheries of the rings.

and extendsinwardly to loosely embrace the shaft 10, and the opposite side wall is provided .with an outwardly-extending flange 13 to receive the detachable side cover-plate 14,,which latter is made in halves, formed with an inwardly-extendin flange to engage the flangelS of the ox, and removably secured thereto with screws 15. A boss 16 is formed upon the upper half-box andprovided with a feeding-orifice for supplying suitable lubricant to the interior of Patented Apr. 19, 1910.

the bearing, a detachable cap 16 closing said orifice.

Within the box is rotatably mounted a two-part retainer or spider 17, comprising jection of said journal-ends beyond the pe- The rollers are held in the retaining-rings against displacement by the contracted peripheral opening of the bearings, saidbearlngs loosely engaging the journal-ends of the rollers and permitting the latter to transfer the working load be tween the shaft 10 and the bear'ng-surfaces '9, which in operation causes a re atively slow rolling contact between the latter and the journals of the rollers and also a slow rotation of the retainer within the box. 1

It will be readily seen that the separate halves of the box may be readily adjusted about the shaft without disturbin the position-of the latter, and that the ha f-sections of the retainer may likewise be adjusted without displacing the rollers therein.

In Fig..4 is shown a modification of the roller-bearing as appliedto a wheel 24, having a continuous rim and arranged to rotate about a fixed axle 25, the annular bearingsurfaces 26 and 27 being continuous as 'are also the retainer-rings 28 and the cover-plate 29. The rollers 30 are mounted in the retainer-rings in the manner previously described, and the interior parts maybe readily removed from the wheel or adjusted upon the shaft by the removal of the cover-plate 29 and the annular bearing-surface 27.

What I claim as my invention and desire to secure by Letters Patent, is

1. In a roller-bearing, the combination with an axle or shaft and a relatively-rotatable wheel or box provided with interior annular bearing ledges concentric with said shaft, of a retainer rotatably mounted in said wheel or box and comprising a pair of rings spaced apart in alinement with said bearing-ledges and connected together with cross-tics, said retainer-rings being provided with journal-bearings having restricted openings cutting the peripheries of said rings, rollers mounted in the wheel or box and engaging the shaft, and laterally-extending journal-ends formed on the rollers and rotatably mounted in the journal-bearings of the retainer-rings for rollin engagement with the bearing-ledges of the wheel or box.

2. In a roller-bearing, the combination with an axle or shaft and a relatively-rotatable wheel or box provided with detachable interior annular bearing-ledges concentric with said shaft, of a retainer rotatably mounted in said wheel or box and comprising a pair of rings spaced apart in alinement with said bearing-ledges and connected together with cross-ties, said retainerrings being provided with journal-bearings having restricted openings cutting the .peripheries of said rings, rollers mounted in the wheel or box and engaging the shaft, and laterally-extending j ournal-ends formed on the rollers and rotatably mounted in the journal-bearings of the retainer-rings for rolling engagement with the bearing-ledges of the wheel or box.

3. In a roller-bearing, the combination with an axle or shaft and a relatively-rotatable wheel or box provided with interior annular bearing-ledges concentric with said shaft, a retainer rotatably mounted in said wheel or box and comprising a pair of rings spaced apart in alinement with said bearingledges and connected together with crossties, said retainer-rings being provided with journal-bearings having restricted openings cutting the peripheries of said rings, rollers mounted in the wheel or box and engaging the shaft, laterally-extending journal-ends formed on the rollers and rotatably mounted in the journal-bearings of the retainer-rings for rolling engagement with the bearingledges of the wheel or box, said box being rovided on one side with an integral wall oosely embracing the shaft and upon the opposite side with a projecting fiange, and a side cover plate detachably connected to said projectim flange.
